Restanza

CHICAGO, June 2 /PRNewswire-FirstCall/ -- Advanced Life Sciences Holdings, Inc. announced today that the FDA's Anti-Infective Drugs Advisory Committee voted in the majority that Restanza(TM) (cethromycin) demonstrated safety for the outpatient treatment of adults with mild-to-moderate community acquired pneumonia (CAP) (11 positive, 3 negative, 1 abstaining). However, the committee voted that Restanza did not demonstrate efficacy in the treatment of CAP (3 positive, 11 negative, 1 abstaining).

"We believe in Restanza's potential and remain committed to its development. We were particularly encouraged by the supportive comments of several members of the committee relative to their positive review of the safety profile of Restanza, the therapeutic need for more effective treatments for CAP and their interest in seeing the company pursue further development," said Dr. Michael Flavin, Chairman and CEO of Advanced Life Sciences. "As we have throughout the review process we will continue to work closely with the FDA as they complete their assessment of the Restanza new drug application (NDA)."

Although it is not binding, the Committee's recommendation will be considered by the FDA as it completes its review of Restanza's NDA in CAP. The FDA has established a Prescription Drugs User Fee Act (PDUFA) date of July 31, 2009 for the Restanza NDA.

About Restanza

Restanza is a novel, once-a-day, oral antibiotic that is under review for approval by the FDA for the treatment of CAP. It has shown higher in vitro potency and a broader range of activity than macrolides against Gram-positive bacteria associated with respiratory tract infections, and, again in in vitro tests, it appears to be effective against penicillin-, macrolide-, and fluoroquinolone-resistant bacteria. Restanza's demonstrated potency and ability to overcome bacterial resistance may be due to its mechanism of action resulting in specificity for its bacterial target. In addition to its utility in CAP, Restanza is also being investigated for the prophylactic treatment of inhalation anthrax post-exposure. The FDA has designated Restanza as an orphan drug for the prophylactic treatment of inhalation anthrax post exposure, but the drug is not yet approved for this or any other indication.

About Community Acquired Pneumonia (CAP)

CAP is the sixth most common cause of death in the United States. CAP and other respiratory tract infections are caused by pathogens such as Streptococcus pneumoniae and Haemophilus influenzae. CAP affects 5.6 million patients in the United States each year, with 10 million physician visits and 2 million hospitalizations occurring annually.

Macrolides and penicillins are currently the front-line treatments for respiratory tract infections such as CAP. As macrolide and penicillin resistance grows and has the potential to cause more clinical failures, there is a need for new antibiotics with unique mechanisms of action that can overcome this emerging resistance.
